Abstract

Purpose: To evaluate reliability and reproducibility of central corneal thickness (CCT) measurement by ultrasonic pachymeter over time in experienced hands. Materials and Methods: Seventeen patients with primary open angle glaucoma (PAAG) or ocular hypertension and 13 healthy volunteers were enrolled in the study. CCT was measured using an ultrasonic pachymeter (OcuScan™ Alcon, Inc, Irvine, California) by one observer, experienced in the technique, and get used with the same device for more than 6 months. Repeat readings were taken at consecutive outpatient visits over one month period. Results: The mean time period between reading 1 and 2 was 30 days. The readings did not show significant difference over the 1-month period. Overall, the mean+SD CCT measurement in the right eye was 549+44.5 μm on the first visit and 540.5+44.3 μm on the second visit (p=0.9). The mean CCT in the left eye was 552+47.6 μm on the first visit and 552+46.6 μm on the second (p=0.9). Consecutive CCT measurements by ultrasonic pachymeter in both healthy subjects and patients with ocular hypertension or PAAG revealed no significant differences separately. Conclusions: Our results indicate that CCT measurement by ultrasonic pachymeter is highly reliable, and that repeated measurements do not show variations over time in experienced hands.

Özet

Amaç: Tecrübeli ellerde ultrasonik pakimetre ile yapılan santral kornea kalınlığı (SKK) ölçümlerinin tekrarlanabilirliği ve güvenilirliğini değerlendirmek. Gereç ve Yöntem: Çalışmaya primer açık açılı glokomu (PAAG) veya oküler hipertansiyonu olan 17 hasta ve 13 sağlıklı birey dahil edildi. SKK 6 aydan fazla süredir aynı aleti kullanan ve ölçüm tekniğinde deneyim kazanmış aynı araştırmacı tarafından, ultrasonik pakimetre (OcuScan™ Alcon, Inc, Irvine, California) kullanılarak ölçüldü. İlk ölçümden bir ay sonra ikinci bir muayenede SKK ölçümleri tekrarlandı. Bulgular: Birinci ve ikinci ölçümler arasındaki ortalama süre 30 gündü. Bir ay içinde takrarlanan ölçümler arası anlamlı bir fark saptanmadı. Birinci ölçümde sağ gözlerin ortalama SKK 549+44.5 μm iken 2. ölçümde 540.5+44.3 μm’du (p=0.9). Birinci ölçümde sol gözlerin ortalama SKK 552+47.6 μm iken 2. ölçümde 552+46.6 μm’du (p=0.9). yine sağlıklı bireyler ile PAAG ve OHT hastaların ölçümleri ayrı ayrı değerlendirildiğinde 1. ve 2. ölçümler arası anlamlı fark görülmedi. Sonuç: Sonuçlarımız ultrasonik pakimetre ile yapılan SKK ölçümlerinin oldukça güvenilir olduğunu ve zaman içinde tekrarlanan ölçümlerde bir farklılık görülmediğini ortaya koymaktadır.
